In Sardinian it is known as Santu Antinu. The rural church of San Costantino, in the territory of Sedilo, overlooks the splendid scenery of Lake Omodeo, the largest artificial 1 reservoir on the Island (for a long time the largest in Europe). Along the perimeter of the sanctuary are arranged the buildings intended for the reception of pilgrims, called cumbessias or muristenes.
The year of foundation is unknown, but it is certain that San Costantino Imperatore is of very ancient origin. The current structure dates back to the 16th century, in Catalan Gothic style, and underwent a renovation in the 18th century. Of the first structure, the quadrangular presbytery with a cross vault and ribs with corbels sculpted at the base remains. The nave, divided into three aisles by pillars and round arches, is barrel-vaulted.
The interior is concluded, close to the presbytery, with a pointed arch. The facade, in exposed red trachyte, has a curvilinear terminal. The portal is surmounted by a tympanum supported by two semicolumns. On the sides and inside the tympanum you will see three niches, while above opens a rectangular window. On the left side of the facade rises a small bell gable. Inside the sanctuary are displayed numerous ex-votos.
Around the church takes place, at sunset on July 6 and at dawn on July 7, s'Ardia, a spectacular horse race in honor of the saint, which recalls the battle of Ponte Milvio between Constantine and Maxentius.
